'+' key doesn't work to create tied note after leaving and re-entering note entry mode

This seems like a pretty minor issue overall, but it's really been impacting my workflow.

This is with the latest available nightly build (from 1 week ago) on Mac OS X 10.9.

Steps to reproduce:
- In note entry mode, enter a note that you want to tie to another note.
- Hit the escape key to leave note entry mode, and go do something somewhere else in the score (e.g. editing a chord symbol).
- Click to select the notehead you just entered; it will turn blue.
- Hit N to re-enter note entry mode. Select the desired note duration (e.g. 6 for half note) and hit + to create a new note of that duration tied to the selected note. Nothing happens.

The workaround is to enter the note you wanted to tie to, leave note entry mode, click the first note, and then hit +, which correctly makes the tie.
